The purpose of this study was to explore among first grade children the relationship between achievement in mathematics and the understanding of the principles of conservation, seriation, and categorization as these are defined by Jean Piaget. Research instruments included those designed by Piaget and the Greater Cleveland Mathematics Tests.…

This paper presents a challenge to a widely cited report by Elkind which states that a large proportion of college students, particularly females, are unable to conserve volume. (BD)

Examines which conservation type (identity or equivalence), if any, is attained at an earlier age. Findings support Piaget's position that identity and equivalence are concomitant developments. (CP)

In order to study possible effects of the degree of perceptual illusion, 64 kindergarten children received tests of quantitative identity and quantitative equivalence for the conservations of number and continuous quantity. (SB)

The authors gave a series of simple demonstrations followed by questions to which ninth grade students provided written answers to assess their ability to perform tasks for conservation of amount, weight and volume. Responses were varied. The paper includes the test form and a few typical answers. (AJ)

The study compared the conservation abilities of 80 prelingually deaf and 80 hearing students (ages 9-12) in the Republic of China. Results indicated a significant difference in conservation ability between groups favoring the hearing students and no significant difference in conservation ability between age levels for the deaf group.

Among results comparing attainment of the conservation concept in blind (N=30), partially sighted (N=50), and sighted (N=40) children (ages 6-15) in Taiwan were that development of partially sighted children was more like the development of sighted than blind children, and that a 1-4 year developmental lag occurred in blind children.

This is a detailed review of studies of extinction of Piagetian concepts, stressing that interpretation of such research is complicated by methodological problems, some avoidable, some intrinsic to the extinction paradigm; and that this paradigm retains the potential for contributing important information about the nature of concrete-operational…

On the basis of these findings, both the measurement techniques of previous studies and Piaget's analysis of seriation are challenged. (Author)

Children who recognize a compensatory relationship between height-width dimensions are more susceptible to conservation training than children who do not recognize this relationship. (Authors)

Hypothesis that non-conservers would give more perceptual than identity arguments, and that conservers would give more identity than perceptual reasons for their judgments was supported by the conservation pretest results. (Authors)

Compensation as assessed by any one test or criterion used is more difficult than conservation. And, the understanding of the compensation principle, as manifested in verbal statements, continues to develop well after the age at which liquid conservation may be taken for granted. (Authors)

The process by which a child learns music is discussed. (CK)

Results confirm the hypothesis that identity and equivalence conservation require different mental processes. (Authors/MB)

Lack of spontaneous" development in the control group children is a matter of practical educational concern because it indicates the extent to which ESN children depend on explicit teaching for their mental advancement. (Author/SP)
